CAN-BODY MACHINE.

SPECIFICATION forming part of Letters Patent No. 598,567, dated February 8, 1898.

Application filed August '7, 1896 To mZZ whom it may concern:

Be it known that we, EDWARD P. HOLDEN and CHARLES M. BROWN, citizens of the United States, residing at Chicago, county of Cook, State of Illinois, have invented a certain new and useful Improvement in Can- Body Machines; and we declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

Our invention has for its object the production of a machine for forming can-bodies and it consists in mechanism for forming the blank, mechanism for shaping the body and engaging the edges of the same, mechanism for bumpin g the edges of the same to permanently engage them, mechanism for fluXing or rosiningthe joint, and mechanism for soldering the sam v The details of the mechanism will be more fully described and claimed.

Fig. 30 is a side elevation of the gaging-fingers. Fig. 31 is a plan View of the same. Fig. 32 is a section of the flux-vat.

In carrying out the invention, A represents the main frame of the machine, of any desirable construction; B, the driving-pulley, located on the shaft B and revolved from any suitable source of power. i

l3 is,a sprocket-wheel on the shaft B, connected by the sprocket-chain B with the sprocket-wheel B on the counter-shaft .13

.0 represents any suitable receptacle for holding the blanks.

A A are suitable standards extending from and a part of the main frame and form the bearings for the main shaft 13; Pivoted to the extensions (1 on the standard A is the arm D, Figs. 1, 14, and 15. The upper end of this arm is provided with two rollers d cl.

, D is a cam-plate on the shaft B, and the rollers cl d travel against opposite faces on this plate D. Thus a revolution of the shaft B causes a reciprocation of the lower end of the arm D. Pivoted to this lower end is a rod D and the latter is pivoted to an arm D on The arm D is in the form of a bell-crank lever and is provided on the end of its arm D with the pawl D (See Fig. 20.) On the shaft D is a disk D pro- 011 the same shaft D are two sprocket-wheels D over which pass sprocket-chains D Figs. 14 and 16, the opposite ends of said chains being passed over sprocket-wheels D supported from the arm A on the main frame.

It will be seen that by the above-described mechanism an intermittent feed is provided for the blanks, the chains being provided with arms or projections 01 (shown in detail in Fig. 19) for engaging the blanks, and a pawl D Figs. 14 and 20, being provided to prevent an extended backward revolution of the chain. At this point, however, we desire to call attention to the fact that the notches d are slightly wider than the end 02 of the pawl D. The purpose of this is that when the chain has fed the blank to the desired point through the medium of the movement of the pawlD and the pawl starts back to engage another notch as it rides out of the notch 61 there being a play between the end (1 of the pawl D and the side of the notch which enables the pawl D to draw the disk D a very slight distance back in the direction af the arrow, Fig. 20, and this will of course move the chain correspondingly and will carry the projections 61 away from'the edge of the blank. The desirabilityof this slight backward movement at the end of the normal forward movement will be apparent as the description of the machine progresses.

We will now describe the mechanism for stamping or forming the ends of the blank. (Shown more particularly in Figs. 2, 5, 6, 7, and 8.) On the main shaft B is a crank E, Fig. 6, surrounded by a collar E, the latter provided on its end with a pitman E having on its end a ball E adapted to fit into a corresponding ball-socket on the cross-head E The collar E is split, and the tightening-collar E is provided with a set-screw E, so that by tightening the set-screw the pitman may be held in the collar E by means of the set-screw in addition to the screw-threads. The crosshead E is shaped as shown in Fig. 5, with a bumper portion E the ways E and the portion E", to which the forming-die is engaged.

E E are dies shaped to fit the correspond ing stationary dies E E as shown in Fig. 8, the dies being held to their respective plates by bolts e.

E is a rodmounted in the bearing E and the lower end passed through the portion E of the cross-head. On the lower end of this rod is a block E and on the stationary frame a corresponding block E A spring E tends to keep the block E in its lowermost position, a collar E limiting the movement, however. Now, as may be seen, as soonas the portion F. strikes the collar E the rod and block will be carried up; but as the cross-head descends to stamp the blank theblank will first engage between the two blocks E and E and be steadied during the process of stamping. Thus a revolution of the crank E operates to force down the dies and form the blank, as

shown by the dotted lines, Fig. 12.

WVe will now describe the mechanism for bending or shaping the blank to form the body. (Shown more particularly in Figs. 9,10, and 11.) On the main shaft 13 is a cam F, provided with a cam-groove F on its face.

F is a rod bifurcated at its upper end, as at F to embrace the shaft B and provided with a roller F which travels in the camgroove F. The result of the revolution of the shaft Bis a reciprocating motion for the rod F in the direction of arrows X, Fig. 9. Pivoted to the arm a extending from the main frame A, is an arm F one endfbeing slotted to receive the pivot f, that engages it to the end of the rod F while at the opposite end are provided two arms F F, Fig. 9. The pivotf is mounted on a block T, that embraces the end of the rod F A spring T normally keeps the block T at the lower end of the rod F but if the mechanism should he clogged by a misplaced blank or otherwise this spring will yield and thus save the balance of the mechanism.

F is the horn around which the blank is folded.

F F are wings. Each wing is provided with a projection f to which the respective arms F F are pivoted.

The construction of the wing F and its connecting-arm is as follows: f Figs. 9 and 11, is a fitting shaped at each end to loosely embrace the rod f. The upper end of this fitting is pivoted at f to the arm f on the wing F On the rod f are two sets of nuts f f, each set adapted to bear on its respective end of the fittingf f is a spring, one end bearing on the shoulder f and the other end bearing on the lower end of the fitting f It will be observed that between the nuts f and the end f of the fitting f is a slight distance or play, the result being that as the wings are thrown up around the horn the wing F will be carried slightly in advance of the wing F until the blank and wing come to a bearing on the horn, when the spring will yield slightly to accommodate the full play of the arm F.

We will now describe the mechanism for flattening or bumping the seam after the body has been folded around the horn. As before explained, E, Fig. 5, carries the bumper G. This bumper portion E is slotted on its under side, and the bumper-steel proper, G, is

held therein by the set-screw G. Above the bumper steel G and between it and the bumper portion E is a wedge G adapted to be forced in or out above the bumper-steel by the set-screw G a set-screw G being pro vided to additionally lock the wedge in'position.

As above explained, the bumper-steel and, dies are carried on the same cross-head, so that while one blank is being shaped by the dies the vertical movement of the pitman h operates the bumper-steel to lock the contiguous edges of the blank into a seam, as shown in Fig. 13.

G Fig. 9, represents ablock stationary on the main frame A, to which the wings F F are pivoted. In order that the blank may be fed under the horn F mechanism is provided for raising said horn slightly, and this we will now describe.

G Figs. 5, 21, 22, and 23, is an arm rigidly connected to the shaft G carried by the main frame A. On the end of this arm G the horn F is carried, as shown in Fig. 23. On the shaft G is an upright arm G provided on its upper end with a roller G", which bears upon the cam G on the main shaft 13. Thus a revolution of the cam G acts to tilt the arm G and this tilts the arm G and lifts the horn F In order that when the blank is fed under the horn it may be straightened and held in its proper position until the horn drops and clamps it, we provide the gagingfingers G As shown in Figs. 30 and 31, these fingers are engaged to a shaft G which is supported by the main frame A. On this shaft is also an arm G the outer end of which rests on a setscrew G and is normally held thereto by the spring G As the chain D feeds the blank against these fingers, if the blank is not in its proper position, the fingers straighten and hold it where it should be until the horn by dropping clamps it. In order that the blank as it is fed forward may have a constant friction on it to prevent its moving too far forward and also to hold it in place in other directions, we provide the pin g, Fig. 5, having a beveled face g toward the direction from which the blank approaches. This pin works in a socket 9 (shown in dotted lines,) carried by the frame A, a spring 9 being provided to keep the pin normally in its upper direction and a collar g bein g provided, against which the end ofthe spring may bear. As soon as the seam has been bumped, as above explained, the chains D carry it off from the horn F and onto the horn H, where it is finned or ,rosined. This horn H is what may be termed-a compound construction. It is composed of a cylindrical portion H, Fig. 7, and three parallel strips H, H and H supported from the cylindrical portion H by the pieces h. The cylindrical portion H is provided with a groove 72/, in which the seam of the can travels. The strips H H H act to steady the can as it passes through the successive operations. The horn H is engaged to the horn F by the loose hook-joint H Fig. 5.

The mechanism for accomplishing the fluxing we will now describe. It is shown more particularly in Figs. 24c and 25. On the main shaft 13 is an eccentric K, surrounded by the collar K, a rod K being attached to the colcar. Supported by the bearing K extending from the main frame, is a counter-shaft, (indicated by the dotted lines K, Fig. 25.) On this shaft is an arm K to which the end of the rod K is pivoted. Keyed to this shaft is an arm K. On this shaft, but stationary with respect to the bearing K is a sprocketwheel K andon the outer end of the arm K is a bearing K carrying a shaft (indicatedby dotted lines K") having on its end the sprocket-wheel K a sprocket-chain K connecting the sprocket-wheels K and K 011 the shaft K is also provided an arm K having on its lower edge a fluxing material K such as felt, wick, or any porous substance. This felt is clamped in the arm K by the screws K.

K is a vat or receptacle containing the liqu d flux supported by the main frame. In

the vat above the liquid'is a perforated diapliragm K and above this diaphragm is a pad of felt or the like K Now, as will be seen, a revolution of the eccentric K operates to give the rod K a reciprocating motion in the direction of the arrows y, Fig. 24, and

this operates to tilt the crank-arm K which in turn oscillates the arm K. The wick K being mounted on the shaft K and the latter being engaged by the sprocket-chain K- with the stationary sprocket-wheel K as the arm K is oscillated back and forth the arm K and wick K will always be maintained in a vertical plane, thus operating to bring the fl-uXing-stripK alternately against the pad K and against the seam of the can. As soon as the cans are fluXed they are carried forward one more movement by the chains D". At this point they are picked up by the endless carriers J, Fig. 29, the inner ends of the chains being supported by the sprocketwheels J, Fig. 3, and the outer ends by the sprocket-wheels J Fig. 29. On the end of the shaft 13 is a beveled gear J meshing with the beveled gear J on the vertical shaft J On the upper end of this shaft J is located one of the sprocket-wheels J On the shaft J is also a gear. J which meshes with the gear J 7 on the corresponding vertical shaft J and on the upper end of the latter is the other sprocket-wheel J Thus a revolution of the shaft B operates to move the sprocketchains J. The latter are provided at intervals with projections J to engage the canbody and push it along over the horn. Obviously the distance between the projections J 9 on each chain is thedistance traveled by the chain for one revolution of the shaft B, so that by properly arranging the parts the can-body will be picked up by the chains J as soon as they have been thrown forward by the last movement of the chains D.

We will now describe the soldering mechanism. Extending the length of the machine and supported by the main frame are two longitudinal supporting-pieces N, which support the solder-cutting mechanism and the soldering mechanism. Extending from these supporting-frames N, Fig. 27, are arms N, having on their ends rollers 11, adapted to keep the soldering-horn H in a central position, andN is a wheel journaled in the main frame and adapted to support the outer end of the horn H. Extending also from the frames N are arms N adapted, as hereinafter explained,

to support the soldering-irons and adapted.

also to support the solder-cutting mechan ism. This mechanism is shown more particularly in Figs. 26 and 27, the solder feeding and cutting mechanism being shown in Fig. 27. On the shaft 13 isa cam M. M is arod slotted in its lower end, as at m, to embrace the shaft B and provided with two rollers m and m adapted tobear upon the edgeof the cam M. Thus, as will be seen, a revolution of the shaft Bgives the rod M a vertical reciprocation. Pivoted on the countershaft M (the latter supported on the arm N is an armor lever M provided on its end fed down to the soldering-iron.

with a slot m On the rod M is a pin m, that enters the slot m and is suitably engaged therein by a nut.

Pivoted to the frame N 4 at nis an arm M the free end of this arm M being connected with the rod M by a link M Working vertically in the frame N is a cutter-knife M the latter engaged to the arm M by a slotted engagement, as at M Pivoted to the frame N is a roller 0 and another roller 0', the peripheries of the said rollers being grooved and adapted to engage the solder-wire P and feed it. On the shaft of the roller Ois a ratchetwheel 0 engaged to the roller 0, and on the arm M is a pawl 0 adapted to engage the ratchet-wheel 0 so that when the arm M is raised the roller 0 will be revolved and the solder-wire P fed the requisite distance. The slotted engagementm is provided, so that the length of solder-feed may be varied.

O is a trough or chute below the solderwire, into which the cut piece drops and is The operation of this soldering mechanism will at once be seen. A revolution of the shaft B reciprocates the rod M vertically, and this tilts the arm M and feeds the solder-wire. 'As the rod Mcomes down it draws down the arm M and causes the knife M to cut the solder, and the latter drops down into. the trough O and is fed to the soldering-iron.

Q, Fig. 28, represents what may be termed soldering-iron boxes, each provided in its lower edge, Fig. 27, with a soldering-iron Q. These soldering-irons and their boxes rest upon the soldering-horn H and are steadied in position by the frame Q ,.extending along the sides, and they are prevented from longitudinal movement by the frames Q Fig. 26, extending across from one frame Q to the other at each end of the series of solderboxes. On the end of the forward solderingiron, Fig. 28, is a soldering-pot Q having a slot Q in the bottom.

Q Fig. 26, are supply-pipes for gas or other fuel and air, and Q are heating-irons or bur-ners. As the solder runs down the chute 0 into the solder-pot Q it is melted and drops through the slot Q onto the can-seam, the can-body being forced along, as beforeexplained, by the sprocket-chains J. After receiving the solder it passes successively under the four soldering-irons Q, where the solder is thoroughly soaked into the seam. Supported on the frame Q is an arm R, and pivoted to the outer end thereof is an arm R, and this arm R is provided on its end with a suitable wiper R The form of wiper which we have used and which we prefer is a block of soft steel or iron made concave on its under side to fit the convex surface of the canand heated from a suitable burner R This block of hot steel or iron passing over the seam wipes off the surplus solder and gives a finished appearance to the can.

It is obvious that many details of construction of our machine might be altered without departing from the spirit of the invention, and we would have it understood that we contemplate the substitution of mechanical equivalents for the particular devices shown by us for accomplishing the various steps in the treatment of the blank from its insertion in the machine to its discharge.

WVe also desire to call particular attention to the shape of the blanks after they have been stamped to form the seam, as shown in Figs. 12 and 13. By forming on one side or one edge a raised portion S in addition to turning the edges, as at S, to form the look when the bumper comes down to engage the two edges S together it will flatten out the raised portion S, and thus increase the diameter of the body over the diameter of the horn, so that whereas in previous machines they have been obliged to reduce the diameter of the horn to enable the can-body to be slipped OK after the seam has been formed we can make the diameter of our horn fixed and can easily slip the body off from the horn, because of the fact that the relative diameter of the body has been increased.
